LED冷光美容灯两种光分别为：
?1、Rray(Red 红光)????????????????2、Uray (Uv 蓝紫光)

1、R--ray：红光的波长频率是628—635nm，医学治疗时证明，红光在治疗很多疾病中都是很有效的，被称为生物活性光，可以加快所有活性组织代谢过程活性组织的生长过程为1、萌发期2、成熟期 3、衰退期加快此循环皮肤的状况可以得到很大程度的改变。
主要功效：美白、淡斑、祛皱、补水，修复受损皮肤，收细毛孔、紧实皮肤、祛痘。

2、U--ray：蓝紫光是利用波长范围在415—450nm的窄谱紫光快速有效地抑制炎症。在痤疮的形成过程中，主要是痤疮丙酸杆菌在作怪，而紫光可在对正常皮肤组织毫无损伤的情况下高效的破坏这种细菌，最大限度的减少痤疮的生成。在很短时间内使炎症期的痤疮明显减少至
痤疮是皮脂腺最常见的一种疾病，其表现为粉刺、炎性丘疹、脓丘疹或脓疱、结节及囊肿等，愈后可遗留萎缩性或增生性瘢痕，患者精神压力大。痤疮的形成主要是由痤疮丙酸杆菌（压氧菌）感染所致。

3、M--ray：混合光是红光与紫光的双频光，它综合了两种光的功效，故祛痘的同时也可以祛痘痕。对严重型的痘痘、暗疮有着特别好的治疗和修复作用。

前言
LED 是英文中Light Emitting Diode的简写，它是新兴的发光体，具有电光极率高，体积小，寿命长，电压低、节能环保等优点。LED的发展受到国内外的普遍关注。新产品、新技术层出不穷。近年来，LED产业发展迅速，光效不断增加。如今LED已经在众多场合得到大量应用。我公司经过多年研究开发出一种LED脉冲冷光美容灯。

简介
发光二极管（LED）是一种能把电能转化为光能的固体器件，它的结构主要由PN结芯片、电极和光学等系统组成。LED的基本工作原理是一个电光转换的过程，当一个正向偏压施加于PN结两端，由于PN结势垒的降低，P区的正电荷将向N区扩散，N区的电子也向P区扩散，同时在两个区域形成非平衡电荷的积累。由于电流注入产生的少数载流子相对不稳定，对于PN结系统，注入到价带中的非平衡空穴要与导带中的电子复合，其中多余的能量将以光的形式向外辐射，电子和空穴的能量差越大，产生的光子能量就越高。能量级差大小不同，产生光的频率和波长就不同，相应的光的颜色就会不同。

LED脉冲冷光美容灯的美容原理
采用特定频率、特定波长、特定脉冲、特定颜色照射于皮肤，可明显促进新组织细胞的生长，使皮下的胶原质的再生速度迅速加快。LED冷光光子对于治疗严重烧伤、骨骼和肌肉萎缩、皮肤嫁接和促进组织再生均有潜在的神奇效果。常规热光美容祛痘方法需要耗时20~30小时，而采用LED脉冲冷光美容只需5~6小时。对于新陈代谢不畅而引起的肤色晦暗问题只需5次光照，即可有明显的改善。几乎所有的面部皮肤问题都可以用冷光美容灯改善甚至消除。

光动力的物理、化学和生物作用

1、生物组织中的内源性或外源性<光敏物质>受到相应波长(可见光、近红外光或紫外光)光照射时，吸收光子能量，由基态变成激发态，处于激发态的<光敏物质>很不稳定，迅速经过物理退激或化学退激过程释放出能量而返回基态。
2、其物理退激过程可以产生荧光，通过分析荧光光谱能进行疾病的诊断。
3、其化学退激过程可以产生大量活性氧，其中最主要的是单线态氧，活性氧能与多种生物大分子互相作用，影响有病损的细胞结构和功能，因而产生治疗作用。

光动力治疗原理
1、它是一种光疗措施，应用低能量的纯红光对皮肤进行病变治疗及施以护理。
2、LED光疗可刺激皮肤纤维细胞原产生胶原和弹性蛋白，它不象激光需依赖高能量的烧灼性冷凝作用。
3、LED启动人体将光能转换成细胞的能量而不会造成组织的热损伤。

光动力工作原理
1、LED光动力美容灯由蓝宝石芯片和红宝石芯片共同组成的LED半导体发出纯度达99％以上的光动力，深入肌肤进行相关的治疗和保养。

LED Skin Rejuvenation Lamp

Over time, our skin becomes less elastic. Smoking, stress, sun exposure, excessive alcohol, pollutants in the air and illness all conspire to create lines, wrinkles and scars. Skin changes may be part of the natural aging process, but you don’t have to like it.
A new procedure called LED Skin Rejuvenation uses natural, variable wavelengths of light to gently stimulate or inhibit cellular activity to reduce the signs of aging.

What is LED Skin Rejuvenation?

LED Skin Rejuvenation is the interaction of light, delivered through Light Emitting Diodes (LEDs), to activate cell receptors causing them to produce collagen or multiply. One of the original applications for LEDs was PhotoDynamic Therapy (PDT), using photo-activated creams for the treatment of actinic keratosis and pre-cancerous lesions.

How are LEDs different from Laser and Intense Pulsed Light (IPL) therapy?

Other light-based skin therapies including intense pulsed light and laser treatments rely on thermal injury to the skin’s collagen, water or blood vessels to create changes in the skin appearance. LED Skin Rejuvenation does not rely on thermal energy and the related tissue trauma to effect change. Therefore, patients are not subject to the variables associated with wound healing.

How does LED Skin Rejuvenation work?

LEDs offer a totally natural, non-ablative method for skin rejuvenation. The light from the LEDs interacts with cells and stimulates them to produce new collagen and elastin. Studies confirm that the same LED energy can be used to inhibit collagen formation, which can be helpful in the treatment of scars. By manipulating the wavelengths, cells can be turned on and off. Yellow light LEDs are used for photo-rejuvenation. Blue light LEDs are used in the treatment of acne. Red light LEDs are used for PhotoDynamic therapy.

How many treatments will I need?

Typically treatments are spread over several months. The number of treatments and the treatment times will vary depending on the problem being treated, the amount of surface area treated and the area treated. Since the results are progressive, you will notice more correction with each treatment. As full correction approaches, treatment intervals can be expanded to three to six month intervals. Since the skin continues to age, maintenance treatments will be required.

Will the treatments hurt?

No. The treatment is very relaxing. The delivery of the LED energy to the skin is completely pain free. The energy generated by the LEDs is cool and gentle enough to treat all ethnic skin types.

Can I have LED Skin Rejuvenation with other treatments?

Yes. LED Skin Rejuvenation can be administered alone or in conjunction with other treatments. It is highly complementary with other skin treatments such as Botox and dermal fillers as well as non-ablative laser and IPL treatments. Cosmetic surgeons worldwide are beginning to choose LED Skin Rejuvenation as one of their preferred treatments for fine lines, hyperpigmented lesions (brown spots and freckles) and other skin problems associated with photoaging.

What are the benefits of LED Skin Rejuvenation?

Treatments are less expensive than other light based therapies. The main benefit is a reduction in the appearance of fine lines, wrinkles, freckles, brown spots, scars and the amount of redness. In addition, the treatments are pain free with no downtime at all.

What will I feel like after my treatment?

Most patients return to normal activities immediately. What patients like the most about LED Skin Rejuvenation is that treatments are fast and they don’t have to miss any activities.

The light delivers 405 nm blue light for the treatment of acne and 627 nm red light for skin rejuvenation.

Gentlewaves is marketed as a photomodulation device that uses low-intensity LEDs in a proprietary pulsed "code" as antiaging therapy.

It is claimed to "energize" mitochondria, send cell signals to cell receptors, increase/decrease gene activity in DNA, and thus reverse the appearance of aging and photoaged skin. It incorporates a skin care kit designed to enhance and maintain the results of the treatment, which includes a cleanser, a daily facial lotion, a nightly facial lotion, and sunscreen. The effectiveness of this device is documented by histology exhibiting new collagen formulation, high resolution ultrasound, and PRIMOS digital surface profilometry.

February 4, 2007 -USA Weekend Magazine:Light That Can Cure You
"Exciting new research provides doctors with an alternative treatment to drugs or surgery for ailments ranging from acne to Alzheimer's... Acne, wrinkles, viruses and more can be treated with light. Healing the human body with a beam of light sounds like something out of a classic Star Trek episode. But even Dr. McCoy never dreamed of the futuristic ways that today's doctors are finding to use different kinds of light in medicine. Researchers are exploring everything from penetrating beams of light that seem to repair heart tissue after a heart attack to "light therapy" that appears to improve Alzheimer's patients' ability to sleep through the night. Doctors are remedying the side effects of cancer treatments, severe acne and other ailments just by shining high-intensity light in varying colors on the affected area..."see article

January/February 2004 -Rehab Management:Therapeutic Light
"Light is a form of energy that behaves like a wave and also as a stream of particles called photons. The development of monochromatic light sources with single or a narrow spectra of wavelengths paved the way for studies, which continue to show that appropriate doses and wavelengths of light are therapeutically beneficial in tissue repair and pain control. Evidence indicates that cells absorb photons and transform their energy into adenosine triphosphate (ATP), the form of energy that cells utilize. The resulting ATP is then used to power metabolic processes; synthesize DNA, RNA, proteins, enzymes, and other products needed to repair or regenerate cell components; foster mitosis or cell proliferation; and restore homeostasis. Other reported mechanisms of light-induced beneficial effects include modulation of prostaglandin levels, alteration of somatosensory evoked potential and nerve conduction velocity, and hyperemia of treated tissues. The resultant clinical benefits include pain relief..."see article
